Sunan an-Nasai Book 49, Hadith 5391

قَالَ الْحَارِثُ بْنُ مِسْكِينٍ قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ الْقَاسِمِ، حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، قَالَ كَانَ الْفَضْلُ بْنُ عَبَّاسٍ رَدِيفَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَجَاءَتْهُ امْرَأَةٌ مِنْ خَثْعَمٍ تَسْتَفْتِيهِ فَجَعَلَ الْفَضْلُ يَنْظُرُ إِلَيْهَا وَتَنْظُرُ إِلَيْهِ وَجَعَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصْرِفُ وَجْهَ الْفَضْلِ إِلَى الشِّقِّ الآخَرِ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّ فَرِيضَةَ اللَّهِ عَزَّ وَجَلَّ عَلَى عِبَادِهِ فِي الْحَجِّ أَدْرَكَتْ أَبِي شَيْخًا كَبِيرًا لاَ يَسْتَطِيعُ أَنْ يَثْبُتَ عَلَى الرَّاحِلَةِ أَفَأَحُجُّ عَنْهُ قَالَ ‏ "‏ نَعَمْ ‏"‏‏.‏ وَذَلِكَ فِي حَجَّةِ الْوَدَاعِ‏.‏

It was narrated that 'Abdullah bin 'Abbas said:"Al-Fadl bin 'Abbas was riding behind the Messenger of Allah [SAW] when a woman from Khath'am came to ask him a question. Al-Fadl started looking at her, and she at him, and the Messenger of Allah [SAW] turned the face of Al-Fadl the other way. She said: 'O Messenger of Allah, the command of Allah, the Mighty and Sublime, to His slaves to perform Hajj has come while my father is an old man, and he cannot sit firmly in the saddle; can I perform Hajj on his behalf?' He said: 'Yes.' That was during the Farewell Pilgrimage
